The fuel economy depends on how heavy you are on the gas considering the new HP's. Normal driving in town is goin to loss 1mpg maybe and highway want be affected. A good tune is goin to increase fuel economy from stock but the stall and bigger motor take a little away so it evens out. I have a 99 extra cab z71 and I was going to put a 6.0 in it with a trailblazer converter and that camshaft with a set of CNC ls1 heads.
I wouldnt put a 3000 in it thats to much. The trailblazer converter is 2500-2800 and is perfect for what your doing.
